BTW, would a 135mm MTB 29er wheel work in a 140mm rear end? Frame is 501
That would be fine. JD Tandems sell 140mm hubs, that's pretty standard size for tandems. If your frame really is 80s I'm surprised is 140mm, I thought that was a 00s improvment.
So you don't think pinching 2.5mm each side would be an issue?
